Golf carts are made of various materials including plastic, fiberglass, aluminum, and even wood. When painting over plastic parts, it is very important to use a good adhesion promoter like our Super Stick Adhesion Promoter available in both quarts and gallons. If the plastic pieces have been previously painted and are in perfect condition, you can go straight to paint after using the adhesion promoter. Otherwise, you will need to follow up with auto paint primer and/or a high build urethane primer.
